Debian Bullseye (stable) x86_64 packages are provided via automated builds.

Please see the source releases page for source downloads.

Please see the binary releases page for binary package downloads.

Opensuse packages are available from Opensuse builds thanks to Martin Hauke.

A Fedora package is available from Copr thanks to Emiliano Gonzalez.

An x86_64 AppImage portable binary is also available in the Downloads area (based on Debian 11 release) and will run without requiring installation on Linux distributions newer than Debian 11.

GNU radio 3.10 support is available on a separate branch gr_3.10. This branch is compatible with Debian Bookworm. You will need to build the application from source code using this branch to be able to use it with GNU radio 3.10.

Other Linux distributions: see Building QRadioLink from source
